Forced induction's affect on the nature of the 86

Where did you see in the discussion about trying to exit a turn?

I was mentioning this in the context of revving the car and having the correct gear. An FI car is more forgiving if you have a wrong gear, because it has a better and broader torque curve. It will pull better and you'll have enough torque even with a higher gear. It is not uncommon that so many drivers complain about the torque dip in stock cars. Most of them they don't use the correct gear and many of them were used to drive like this because of older FI cars or bigger engine cars.

I should have been more clear since both of you misunderstood my comment. I have not tried to tune those cars, I was commenting on the stock tune.

Subaru's tuning of the FA20 turbo in the WRX is beyond terrible. It's really incredible how bad it is, which is why I'm glad they did not do that to the BRZ. Selling a car that benefits from a tune, I can understand (GTI, FocusRS, etc.). Selling a new car that requires a new tune is dumb.

I imagine a JRSC would work great (post-warranty LOL).

No it isn't. Wrong gear is wrong gear, period. The guy in the right gear will go faster, FI or not.

Tell this to the people who go FI, because they don't like to downshift constantly for an overtake. Maybe you have in mind only race track driving. On ordinary road there are different driving scenarios. I am not saying here which is good or bad. What I am saying is that going FI changes definitely the nature of the car.

It's your discussion, not mine.

Is there something wrong with not downshifting?

Nothing is forgiven, error is error, wrong gear is wrong, lost speed is lost, FI or not. FI drivers are not dummier than NA drivers, if you mean that.

You'll lose less time with a stronger car. I think it is quite obvious. It seems to me that we are arguing here just for the sake of argument.

I'm gonna let you think about that one

So I figured I would resurrect this thread and spin it off in another direction...

Forced induction does change the character of the car... it makes it a bit more... high-mauntenance...

On top of the regular oil changes, sometimes you do need to fix the neglect precious owners have shown the poor girl. Sometimes after a bad breakup, a girl needs is a little bit of tenderness, love, some kind words of encouragement, and a minor (read 'major') rebuild...

Feast your eyes on the carnage: high speed bearings failed, oil slinger found gears, balls left races, all bad news. Except for the one piece of good news: the gears, housing, compressor wheel, and volute are all fine. That means its supercharger rebuild time!

It was three laps behind a pace car, no passing allowed, but I was able to open it up through a few sections and really got a good feel for the car on the limit. Let me preface this by saying I haven't done the same in a N/A car, but I think the car really needs the extra power. It has so much going for it chassis-wise already, but the extra torque you get from FI makes the car feel so more grown up.

I know there are a lot of people out there that say you'll blow up your engine if you put forced induction on it, but i think there is definitely a right way to do it. Not too much psi, especially at lower RPM, and supporting mods like a catch can will help keep the engine internals happy. Honestly, the car doesn't need a whole lot more power to really liven it up, but a little bump is exactly what the car needs.

If you are on the fence about getting forced induction, go for it already!

I agree with this... I had stock, then did headers and flex fuel.
That mod was brilliant for a road car and I encourage everyone I can to do that at least. (If anything just to fill up the torque gap).

But then a couple of years later I’ve add a SC and I’m super happy with it.

It’s still an 86 in feel and drivability etc, but you’ve just got the nice extra layer of power for overtaking or having fun. I’m glad I did it and the chassis can easily handle it.
